Definitions
- the invention relates to a device for connecting subjected to axial length changes pipelines, especially high pressure pipelines, which are laid, for example, in shafts of mines.
- Manhole lines are also referred to as 'manhole lines'.
- Manhole lines are used not only in German, but also in the foreign coal industry, they must be conveyed over many hundreds of meters to the corresponding underground mining operations. There is often a problem regarding the linear expansion of such installed manhole lines.
- Such a length expansion can be compensated in the form of hoses, which are installed approximately every 100 m, or by means of known expansion spirals, which can compensate for a length of 40 to 50 mm per 100 meters.
- the invention is therefore an object of the invention to provide a device for connecting subjected to axial length changes piping available, which can also be used for very high pressures, has a simple structure and yet can be dismantled for maintenance and cleaning purposes.

- the invention has recognized that it is possible to provide the telescopic connections always the Rohrinndendruc ⁇ exposed frontal annular surfaces each with a corresponding compensating element, which in turn has a pressurized frontal annular surface, but in the opposite direction.
- the individual devices behave neutrally, so that an addition of individual smaller Druckbeiastungen is reliably excluded in a particular direction.
- manhole lines often have lengths of significantly more than 1,000 meters, so length changes without corresponding balancing elements would result in longitudinal expansion of the line which would undulate the duct to cause buckling, even avoiding brackets could tear out of the shaft wall.
- the outer sleeve is screwed to the sliding sleeve and / or the ring with the tubular element. It is understood that corresponding sealing elements are present at the end of the screw.
- the screw has the advantage of a defined position, since the two parts to be joined together when mounting the device in the desired position (as end position) can be brought.
- Another teaching of the invention relates to a device which can be used between two pipe couplings having line ends and thus end has corresponding coupling elements.
- a connection with pipe couplings and clamps is appropriate so that the individual elements can be easily assembled and disassembled, for example, to replace seals.
- the pipe element at its end opposite the flange on a pipe coupling element.
- Pipe coupling element on a longer pipe coupling flange in which the end of the tubular element is screwed.
- This Pipe coupling flange may, as well as the outer sleeve and / or the ring, evenly distributed over the outer circumference arranged blind holes have to facilitate the screwing and in particular the screwing for maintenance purposes.
- the sliding sleeve at its open end on an adapter element whose inner diameter corresponds to the pipe and which projects into the sliding sleeve.
- both the adapter element and the sliding sleeve each have a flange, so that the adapter element can be connected to the sliding sleeve via a pipe coupling clamp or fferrohrkupplung together.
- the adapter element at its end opposite the sliding sleeve has a pipe coupling element which also acts as a pipe coupling element
- Pipe coupling clamp or can be formed as a threaded pipe coupling.
- the outer sleeve From the medium in the line acted upon part of the outer sleeve remains pressure-free, the outer sleeve according to a further teaching of the invention has a plurality of circumferentially spaced openings through which the air can escape with changes in length of the tubular element.
- the openings are expediently designed as bores. It will be understood that between each two interengaging parts at least one seal is arranged in respective grooves, wherein preferably O-rings are used as seals.
- the grooves provided for the sealing rings have a corresponding surface finish.
- FIG. 1 shows a longitudinal section through a device according to the invention in the middle position
- Fig. 2 shows the article of FIG. 1 in its first end position
- FIG. 3 shows the article of FIG. 1 in its second
- FIG. 1 shows the same object, namely the device according to the invention in a middle position (FIG. 1), in the extended end position (FIG. 2) and in the retracted end position (FIG. 3).
- the device initially consists of a first tubular element 1, one end of which is reinforced with a flange 2 and a ring 3 is arranged approximately centrally around its circumference.
- the ring 3 is screwed onto the tubular element 1 in the exemplary embodiment shown, which is preferred so far, for this purpose the tube element 1 provides a corresponding external thread at the desired location (not denoted more closely). Accordingly, the ring 3 has a corresponding internal thread.
- the Rohreiement 1 is now arranged with its flange 2 having the end in a sliding sleeve 4, which in turn is connected to an outer sleeve 5, whose inner diameter corresponds to the outer diameter of the ring 3 and the sliding sleeve 4 finallywandues end has an opening for receiving the tubular element 1 ,
- the annular space formed between the ring 3 and the upper end of the outer sleeve 5 is connected via holes 6, which are distributed uniformly over the circumference of the tubular element i, with the fluid in the pipeline.
- the geometry of ring 3 and outer sleeve 5 is selected so that the pressurized annular surface of the ring 3, which is designated as surface F 2 , substantially the same should be big as the ring surface Fi, for - any Position of pipe element 1 to sliding sleeve 4 - to allow pressure equalization in the axial direction. In this way, a structure of unilaterally adding axial pressure can be reliably prevented.
- the shaft line ends which are referred to above with egg and below with E 2 , pipe coupling elements.
- Dementsprecnend a pipe coupling element 7 is screwed onto the upper end of the tubular element 1, which is formed in the illustrated case as a plug-in part and corresponds to the formed as a sleeve part end of the manhole egg.
- the pipe coupling element 7 in this case has a longer pipe coupling flange 8, in which the screw connection with the end of the tubular element 1 via a unspecified thread.
- Pipe coupling elements 7 and egg are held together in the illustrated case by means of a clamp coupling 9.
- an adapter element 10 whose inner diameter corresponds to that of the pipeline and which has at its end a diameter which corresponds to the inner diameter of the sliding sleeve 4 and projects into this.
- the adapter element 10 has at its upper end a flange 11 and the sliding sleeve 4 at its lower end a flange 12, which are connected to a clamp 13 with each other.
- the adapter element 10 is also provided with a pipe coupling element, in the illustrated embodiment, with a sleeve 14 into which the executed as a plug-in end E 2 of the lower
- Pipe strand is introduced, wherein the two flanges of these parts are connected to a clamp 15. So that the annular space below the ring 3 remains pressure-free even with axial movements of the device in any case, a plurality of bores 16 distributed over the circumference of the outer sleeve 5 are provided in order to ensure a corresponding air inlet or outlet.
- the flanges provided with an internal thread of the outer housing 5 and the pipe coupling flange 8 as well as the ring 3 at its
- At least one seal is arranged in corresponding grooves everywhere between two interlocking parts.
- These seals are expediently designed as O-rings, the associated grooves expediently surface-treated.
- the manhole line itself can be hung on a console K and then hang freely about 100 m, and then open into a next device to compensate for the change in length, which in turn mounted on a standpipe is coupled to a corresponding console.
- the length of 100 m serves only as an example, it can also be only 50 m or even less or maybe even 110 m.
- the use of the device according to the invention also allows that a manhole line no longer needs to be fixed to the wall with every one or every other pipe, since at axial pressure, which is compensated accordingly, buckling of the pipe can be prevented.
- Fig. 2 shows the device according to the invention in the extended state, this corresponds to a shortened upper pipe line. Also in this end position, both annular surfaces Fi and F 2 are pressurized with medium pressure, so that expansion of the upper pipe can be done easily and pressure-free.
- FIG. 3 shows the opposite end position, as it must never occur in normal operation, since here the lower annular surface Fi is in contact with the corresponding annular surface of the adapter element 10 and is therefore no longer pressurized. Therefore, in the design of the dimensions for the inventive device always a sufficient "reserve” provided. Alternatively, it would also be possible to make the upper annular surface of the adapter element 10 conical, so that the Ringfiumblee Fi is pressurized in its final position.
